23.5.2
The internal USB transceiver must be set up before this module can be used. The procedure is
described below. Furthermore, figure 23.20 gives an example of a program that implements the
procedure.
1. Write 1 to the UACS23 bit in the USB AC characteristics switching register.
2. Write 1 to the HOSTPCC bit in the test mode register (TESTMODE).
A special sequence can be used to ensure that these bits are not erroneously overwritten. The
sequence for writing is given below.
1. Write 1 to the UACKEY0 and UACKEY1 bits in the device control register (DVSTCTR).
2. Write 1 to the HOSTPCC bit in the test mode register (TESTMODE).
3. Write 0 to the UACKEY0 and UACKEY1 bits in the device control register (DVSTCTR).
